More an more Bugs(?) with every update????? ;(

In the past, the Navigator always ran without any problems. Now with every update there are new things that don't work:

1. rather funny: speed limit 255 on "Autobahnen" with no speed-limit (ist not an OSM-Problem - its nearly on every Autobahn with no limit)
2. The navigation voice stopps "talking" after a few minutes (this is definitely due to the latest version - I installed an older one, so it works, then the newest one, then it doesn't work again)
3. Lethal navigation instructions. Here, too, the error lies in the app and not in the OSM data, as this behavior occurs on almost ALL runs with this design. I have already deactivated "turn" in the vehicle profile. Still the same
4. Suddenly "way-signs" (what do you call the signs with the city names on them?) are no longer displayed. I also didn't find a point in the settings.
